Run the rl26. We loaded a Winchester 270 wsm the other day and got 3600 fsp with the 117g Hammer Hunter. This was with some Win nickel brass. Not sure I like it. Start at 68g and work up.So, as quick as a flash my Hammer Hunter 117grn .277 have arrived in NZ. Great service.
I have 2 good loads for my XBolt .270wsm with 129 grn. Barnes LRX, 20 thou off lands, with R17 and R26. I'm guessing that those loads would be good starting points??
